MOLDING-MACHINE.

Specification of Letters Patent.

Registered Sept. 5, 1905.

Application filed September 30,1903- erial No. 175.127.

To all who/1t it warty cone/WW2..-

Be it known thatl, Fnnonmox \V. HALL, a

citizen of the United States, residing at Cami den, in the State of New Jersey, have invented certain new and useful Improvements in Holding-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention to be hereinafter described relates to molding-machines for expeditiously performing the operations incident to the making of molds and assembling the drag and cope sections in the completion of the flask.

The objects of the present invention, generally stated, are to provide a fully-organizcd molding-machine of the character referred to wherein the various operations such as ramming the sand about the patterns, the handling and assembling of the drag and cope sections to complete the flask, the withdrawal of the patterns after the ramming operation, and the movement of the table to position between the ramming devices and to one side for recharging the cope and drag with sandshall be automatically accomplished as 'far as possible with the least attention on the part of the operatives, so that the molds may be readily and expeditiously formed with accuracy.

Other generally-stated objects are to provide simplified mechanically constructed parts adapted for great variety of work and to render the different elements of the structure adjustable to different sizes of molds to be formed. thus imparting to the organized machine a wide range of utility, and to operate the movable parts in the formation of a mold by means of air or other fluid pressure, operation of one part putting into action air or fluid pressure to accomplish the succeeding operation of the next part in the cycle of a mold formation.

Other objects as to the structure of the machine and its function will appear more fully hereinafter.

\Vith these generally-stated objects in view the invention consists of the parts and combinations, as will be hereinafter more fully described in detail and then definitely pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a molding-machine embodying the present invention in one of its preferred forms with some of the piping connections omitted for the sake of clearncss. Fig. 2 is a front elevation thereof. Fig. 3 is a longitudinal sect-ion thereof on line .1 :1 Fig. 1, some of the parts being shown in elevation to more clearly illustrate the structural relation of parts. Fig. #1 is a transverse section of the machine on line 3/ 3 Fig. 2, parts being also shown in elevation for the purpose of clearncss of details. Fig. 5 is a top plan view, some'of the piping connections being omitted for the purpose of clear illustration of structure. Fig. 6 is an enlarged detail front elevation of the top portion of the machine with piping and cover omitted,showing the flask-assembling mechanism and its adjusting means. Fig. 7 is an enlarged detail end elevation of the parts shown by Fig. 6, showing the adjustable character of the flask-assembling mechanism. Fig. 8 is an enlarged sectional detail of the same. Fig. 9 is an enlarged detail front view of the table detached from the machine and showing the drag-section of the flask sustained thereby. Fig. 10 is a detail longitudinal sectional view of the table and the attached drag-section, taken on line of Fig. 11. Fig. 11 is a bottom plan view of the table and attached drag-section of the flask. Fig. 12 is a side or end elevation of the table with the drag-section of the flask attached thereto. Fig. 13 is a transverse section of the table with the drag-section attached, taken on line .r il Fig. 9. Fig. 1 1 is a front view of part of the machine, showing more especially the piping and pipe connection and valves for operating the upper and lower ramming devices, also for blowing out the spruecutter, some of the parts being shown in section. Fig. 11" is adetailview of the means for operating the valves. Fig. 15 is a view similar to Fig. H, but showing in addition thereto part of the piping and connection for operating the flask closing or assembling devices and table-cylinders. Fig. 15 is a front view of a portion of the machine, showing the piping and connection and controlling-valves for operating the flask closing or assembling mechanism. Fig. 17 is a side view of part of the machine, showing more especially the piping and connections :for operating the ramming devices, the flask closing or assembling
